MACHINE FOR STRETCHING WOVEN FABRICS.

SPECIFICATION forming part of Letters Patent No. 230,703, dated August3, 1880. Application m d December 21, me.

To all whom it may concern if Be it known that 1, ROBERT HOLT, ofPaterson, in the county of Passaic and 'State of New Jersey, haveinvented, certain Improvements 5 in Machines for Stretching WovenFabrics, of

which the following is a specification.

My invention relates to that class of machines for stretching andwinding or rolling fabrics in which the edges of the fabric are carriedeach between a belt and the face or periphery of a roll divergent fromthe line in which the fabric moves; and the improvements consist in thecombination, with the stretching devices, of a free vibratory reelhaving its I 5 ribs arranged eccentrically around its axis; in

e the construction of the ribs of the reel; and in the combination, withthe stretching devices and reel, of a heating and pressing drum, to actupon the fabric while the latter is being laid upon the winding-roll.

In the accompanying drawings, Figure 1 represents a front elevation ofmy improved machine; Fig. 2, a top-plan view'of'one end of the same Fig.3, an end elevation of the 2 same, having one of the stretcher-supports.

partially broken away to expose the internal driving-gear; Fig. 4, avertical cross-section of the machine on the line :0 w of Fig. 1; andFig. 5, a perspective view of the reel by which the fabric is supportedin passing through the machine.

The machine consists, essentially, of two divergent wheels or rolls andbelts or bands traveling upon and partially around the same,

3 5 standards or supports for said wheels or rolls capable of beingadjusted longitudinally upon the supporting bed or frame, a vibratingreel to support the fabric between the diverging wheels, a winding-roll,and a heating and pressing drum, together with actuating mechanism forthe variousparts.

Referring to the drawings, A represents a bed or base frame formed orprovided with overhanging longitudinal ribs or ways a, be-

5 neath or against which engage inwardly-extending flanges formed uponthe under side of two supporting blocks .or plates, 12, located respectively at or near the opposite ends of the bed or base frame A, andcapable of adjustment longitudinally thereon. Supported upon series ofclips, 0, as shown in Figs. 1, 2, and

3, this arrangement permitting the horizontal rotation of the supports Bwhen necessary, or the clamping of the same in any desired position; andbolted or otherwise secured upon the top of each base or support B is abent or overhanging arm or standard, 0. (Shown more clearly in Fig. 1.)Each arm or standard U carries at its outer extremity a yoke, F,furnished at both its ends with a belt-pu lley or roller, and supportedin the arm or standard by means of a vertical screw rod or stem, 2,passing upward through the latter, and furnished at the upper side ofthe arm with a nut wheel, 2, by which it may be adjusted vertically.

D D represent two large wheels, which are covered on their peripherieswith rubber or equivalent material capable of taking firm hold upon theedge of the fabric. Each wheel D is secured upon a short horizontalshaft, B, provided with a bevel-pinion, d, and supported in suitablebearings upon the top of the base or support B at one end of themachine, as shown in Fig. 1, and receives a rotary motion through thegearing or meshing of the bevelwheel at with a correspondingly-formedpinion,

d, secured upon avertical shaft, which extends upward through the hollowbase B and receives motion from the driving-power, as hereinafterexplained.

E E represent two belts, of rubber or like material, one of which passesover the upper side of each of the wheels D, and is thence carriedoutward beneath rollers or pulleys 6, held and turning inoutwardly-projecting arms formed upon or secured to the bases or sup- 0ports B, and thence upward and over the rollers or pulleys of the yokeF, as shown in Figs.

3 and 4. Under the above arrangement the belts are caused to travel incontact with the upper faces of the respective wheels D, and to pressagainst the same with a greater or less force, which may be regulated byturning the wheel-nut z, and thereby raising or lowering the yoke F. i

From the above it will be seen that all the parts of the machinedirectly connected with the wheels D and their belts E are mounted uponthe supporting-bases B, and that the wheels derive their motion fromvertical shafts concentric with said bases. It therefore follows thatthe bases may be rotated upon their supporting-blocks b to change thedivergence of the belt-wheels and belts; or the blocks 1), with thebases and attendant parts supported thereon, may be moved longitudinallyupon the base or bed A to vary the distance between them without in anyway interfering with the gearing or the position of the parts sustainedby the bases B.

I, Figs. 1,2, and 5, represents a reel which extends in a horizontalposition between the belt-wheels I), and consists of a central shaft,00, and a series of longitudinal ribs, 2:, supported by radial armsextending from the shaft, as shown. a

As will be more clearly seen by referring to Figs. 4 and 5, the radialarms which project from hubs or bosses on the shaft 00 are of differentlengths, those which support the first or front rib being shortest andthe others increasing regularly in length to the end of the series, thuscausing the libs t' to be arranged eecentrically around the shaft oraxis. By reference to Figs. 1 and 5 it will also be observed that thefirst or forward rib is curved outward, and that the succeeding ribsgradually return to a straight form.

The shaft 00 of the reel is jonrnaled at its ends in uprights orstandards k, which are adjustable longitudinally of the bed A, uponwhich they are secured in the same nianneras the blocks b, in order thatthey may be set to receive reels of differentlengths, corresponding withthe distance between the stretchingwheels, which is in turn regulated bythe width of the fabric and the amount of stretching desired.

The reel I is free to rock or vibrate to a limited extent in itsbearings, and is prevented by an upright, j, from rocking beyond thedesired point.

The eccentricity of the reel, the curvature of its ribs, and its rockingor vibration facilitate the passage of the fabric and produce a muchmore satisfactory result than the ordinary arrangement.

For the purpose of winding or rolling the fabric, I mount in the rear ofthe machine a horizontal roll, to, which receives the fabric fromtherear side of the stretching-wheels and belts; and in order that thefabric may be wound smoothly and compactly and simultaneously dried, Imount below and parallel with the roll to a hollow drum, H, which isprovided at one end with a hollow trunnion, s, for the admission ofsteam or hot air to its interior for the purpose of heating the drum.

It will be observed by reference to Figs. 3 and 4 that the winding-rollis mounted in slotted standards, and that its entire weight restsdirectly upon the heating-roll, so that the fabric, while in a stretchedcondition and during the instant that it is being laid upon the roll, issubjected to the joint action of heat and pressure, and thus laidsmoothly and firmly in place.

I am aware that a act upon the fabric leaving a stretching-machine isnot new; but a peculiarity of my arrangement is that the winding-rolland the heating-roll are arranged in such relation to each other and tothe machine that the fabric is subjected to pressure as it is laid uponthe winding-roll and While extended both laterally and longitudinally,thus insuring the placing of the fabric in a smooth and compact shapeupon the roll.

1n operating the machine, the fabric passes inward between two parallelhorizontal rods, m n, arranged one above the other, as shown in Figs. 1and 4., thence over the reel I, with its edges between thestretching-wheels and belts, and finally between the roll to and drum H,and around the former.

The rods m n are either or both of them furnished with collars Z,capable of being adjusted lengthwise of the rods and clamped at anydesired points thereon, their office being to guide the fabric, thewidth of which they are adjusted to correspond with.

The machine being constructed as above described, motion is communicatedto its various parts from a driving-shaft, h, located at the rear sideof the machine, by means of the gearing and belts represented in Figs.1, 3, and 4, and which I will now explain. The drivingshaft h isfurnished, near one end, with a pinion, 0, meshing with an idler-pinion,g, which, in turn, meshes with and gives motion to a cog-wheel, 0, uponthe shaft of drum H, thus rotating the drum; and said driving-shaft h isfurther provided at its middle with two conical pulleys, h, arrangedwith their bases toward each other. These pulleys h communicate motionthrough belts to two independent step or cone pulleys, g, mounted uponindependent shafts g, located in opposite ends of the bed or base frameA. Each shaft 9 carries a bevel-pinion, f, which meshes with and drivesa horizontal bevel-wheehf, secured upon the lower end of the verticalshaft,which passes upward through the center of the base or support Band carries at its upper end the pinion (1, through which motion isimparted to the large belt-wheels D, as above stated. The pinions f areadjustable lengthwise of their shafts, in order that they may be placedand kept in gear with the wheels funder the various adjustments of thebases B and their attendant parts.

It will be seen that under the above construction each stretching-wheelis driven independently'of the other, and that by shifting thedriving-belts upon the cone-pulleys either stretching-wheel may becaused to run faster or slower than the other, the effect of which is tostretch the fabric more or less at one side or edge than at the other.

The eccentricity of the reel may be produced heating drum or roll to teither by varying the length of its radial arms, as shown, or by varyingthe width of the ribs or blades.

I am aware that the use of reels to support the fabric in connectionwith diverging stretching-Wheels is old, and I lay no claim. broadly,thereto.

My improvements consist in so arranging the reel that it is allowed alimited rocking or vibrating motion on its independent of thestretching-wheels, in arranging the slats of a vibratory reeleccentrically around the axis, and in giving the ribs forms changingfrom curved to straight.

By permitting the vibration it is found in practice that the fabric,which is sometimes full in the center and at other times or at otherpoints full on the edge, is subjected to a more even and uniform strainand delivered in a smoother and better condition, and that this isgreatly facilitated by the eccentricity of the reel and its tendency toturn forward, and by the peculiar form of the slats and their positionsin relation to each other.

One or more of the ribs or blades of the reel may be crn'ved outward, asdesired.

Having thus described my invention, what I claim is- 1. In combinationwith the stretching-wheels and belts and their actuating mechanism, thefree vibratory reel having its ribs disposed eccentrically around theaxis, substantially as described.

2. In a faln-ic-stretchin g machine, a rocking or vibrating reel havingribs on the receiving side curved longitudinally outward and the ribs onthe delivery side straight, or approximately so, as shown and set forth.

3. In an organized machine for stretching, winding, and pressingfabrics, the combination of divergent stretching-wheels, belts actingthereon, an intermediate sustaining-reel, a heating and pressing drumarranged to act upon the fabric while the latter is upon the roll, andactuating mechanism, substantially as described.

The above specification of my said invention signed and witnessed atPaterson, New Jersey, this 14th day of December, A. I). 1878.
